Introduction to OOP

OOP is a programming paradigm that organizes code around objects and their interactions
Key principles: encapsulation, inheritance, abstraction, and polymorphism

Real-Life Examples of OOP

OOP helps model real-world entities like Cars with attributes (color, make, model) and behaviors (accelerate, brake, turn)
OOP is used in:
- Game development (characters, objects, interactions)
- Web development (user accounts, shopping carts, content management)
- Desktop applications (document editors, financial software, media players)

Core Concepts of OOP

Encapsulation

Bundling data (attributes) and methods (behaviors) together within a class
Controls access to data by making attributes private and providing public methods (getters and setters) to access and modify them

Inheritance

Creating new classes (subclasses) that inherit properties and behaviors from existing classes (superclasses)

Abstraction

Providing essential functionalities without exposing implementation details
Uses interfaces to define what a class can do, not how it does it

Polymorphism

Allowing objects of different classes to respond to the same method call in different ways
Two main types of polymorphism in C#:
- Method Overloading: Having multiple methods with the same name but different parameter lists
- Method Overriding: Subclasses redefining inherited methods to provide specialized behavior
